NPE when getting list of instances #478
When I call
This behaviour is not deterministic - there seems to be no reason to appear - doesn't appear after load, after exact time etc. When I get the NPE for the first time, I get it all the next calls until I restart the cluster.
Sorry for the long delay. I'm looking at this bug now.
So if I understand you correctly, the cluster is stable; there are no members joining or leaving the cluster (I'm trying to narrow scope of the cause).
I'm trying to reproduce the error so we can create a fix for it.
